A method is described for seismic imaging including determination of reservoir stresses. The method may include the use of elastic full waveform inversion (FWI), 3-order elasticity, and finite-difference strain calculations. The method may be executed by a computer system.

System and method for deriving reservoir stresses from 4D seismic data

Systems, methods, and mediums may implement obtaining baseline traces of a baseline seismic survey and monitor traces of a monitor seismic survey; employing a computer to align the monitor traces to corresponding baseline traces using an error function having a phase-based component, thereby obtaining an aligned monitor survey; generating with the computer a comparison of the aligned monitor survey to the baseline seismic survey; and using the comparison of the aligned monitor survey to the baseline seismic survey to determine a change in the subterranean hydrocarbon producing reservoir.
